IB LOVVPIIPE-REGEIVING' DEVICE FOR GLASS-BLOWING MACHINES.

Patented Jan. 12, 1915.

Original application filed January 13, 1911, Serial No. 602,532. Divided and this application filed hecember 18,1912. Serial No.737,40 2.

To all whom. it may concern:

Be it known that LBENJAMIN D. CHAM- BERLIN, a citizen ofthe ,United States of America, and a resident of Corning, New

York, have invented certain new and useful.

Improvements in Blowpipe-Receiving Devices for Glass-Blowing Machines, of which the following is a specification.

This invention relates to means for receiving, holding and releasing a removable blow pipe on which a mass of glass is carried, it being especially applicable to the type of machine shown in my prior application, Serial No. 602532, filed January 13, 1911, for apparatus for the production of glass articles, of which this case is a division. The apparatus shown in that application comprises a supporting frame movable through a limited vertical arc and adapted to receive a removable blow pipe, the frame having a substantially horizontal normal position in which the blow pipe is loaded, and is swung from such position to a vertical position in which molding and blowing occurs.

The invention forming the subject-matter of this application relates to the means for securing the removable blow pipe upon the frame in proper operative relation to the air supply thereon and for automatically releasing the blow pipe at certain times, but the invention here.sought to be patented is not restricted in its use to the exact type of machine shown in my prior application.

My invention furtherconsists in the construction, arrangement and combination of the several parts embodied in it as will be hereinafter more fully described and claimed.

Referring to the accompanying drawings in which corresponding parts are designated by corresponding marks of reference,-F1gure 1 is a sideelevation of the machine such as forms the subject-matter of my saidv original application, and having the invention here sought to be patented applied thereto. Fig. 2 is a plan view of a blow pipe frame having my invention applied thereto; and Fig. 3 is a side elevation thereof partly in section.

The machine to which this invention is shown as applied comprises a frame 1, having mounted, in the head thereof, a blow pipe frame .2, means of a trunnion 3.

is during a rotation ofthe cam disk swung through a limited vertical arc to position the glass upon the blow pipe'carrieil thereby in proper operative relation to the mold, and is then returned to its normalposition.

The rotation of the cam disk from the motor is controlled in a proper sequence by,

means of clutch mechanism 11 not neces-.'

sary'to be here described, it being sufiicient to say that thedriving mechanism provides pauses with the blow pipe horizontal, and

vertical.

A blow pipe chuck 15 is mounted upon what may be termed the rear end of the blow pipe frame and consists of a block 15 having mountedin its forwardend, by ball bearings, a-shell 15 in which is pivoted a plurality of jaws 15",'the free ends of which project forwardly and which may be forced inwardly, toward the axial line of chuck, by a sliding collar 15, to engage an annular groove 30 in the upper end of the. blow pipe '30, when the latter has been inserted therein by "an attendant, which is done when the blow pipe frame is substantially horizontal.

Therear inner edge of the collar is beveled as at 15* and by contacting on its rear movement with the rounded outwardly projecting noses 15 on the front ends ofthe jaws closes the latter upon the pipe with sufficient force to clampit securely and to press it rearwardly against apacking 35 to be hereinafter described. The jaws are heldin this clamping position by the inner cylin drical wall 15 ofthe collar, which wall is normal to the arc in which the jaws swing and is by the final rearward movement of the collar brought upon the outside of the noses 15 The gather end of the blow pipe after its oted. at their adjacent ends to the forward end of-a rod 17, mounted in a guide 17 on the blow pipe frame, the rod being projected forwardly by a coiled spring 17 interposed between the guide and a block 17 faston the rod, whereby "the forward ends of the -levers will be pressed together closing the rollers on the blow pipe. For the purpose of separating the pairs of rollers to insert the blow pipe therebetween, the lower endof the block 17, projects'through a slot in the bottom web ofthe blow pipe frame, and

has' oonnected thereto the forward end of a link 31, the rear end of which is connected to the inner end of a hand lever 31* pivoted intermediate of its length at 31 to the bottom web of the blow. pipe frame, the opposite end of the lever extending outwardly.

from the side of the blow pipe frame,.where it terminates in a handle, which when moved forwardly, will, through the connections de-' scribed, separate the rollers. The hand lever has also connected thereto atits outer end a link 32, extending rearwardly and terminating at its rear end in a yoke 52 which engages in the groove 15 'of the chuck collar 15, whereby the same movement of the hand lever 31 which separates the anti-friction rollers of the front pipe support will also cause a forward movement of the sleeve torelease the upper end'of the pipe, thus permitting the ready removal of the latter.

Under certain circumstances it may be desirable to at times free the lower end of the blow pipe so that it may be moved slightly in respect to the blow pipe frame to.

properly aline it with cotiperated mechanisms, for instance, the mold, while holding the upperend of the pipe. In order to admit this when it is desired, the following construction may be used. A lever 33 is pivoted on the bottom surface of the web of the blowing frame near the forward edge. thereof, which lever projects inwardly past the inner edge of the blow pipe frame, and is pivoted to the link 31 where it' crosses the latter, and a cam 33* is fixed upon the upper surface of the hub of the bell crank on which cam. when the blow pipe frame moves into vertical position for blowing, the inner end of the lever is adapted to ride, being shifted thereby to" retract the link 31 whereby the guide rollers will be separated being held in this position during the molding by the cam 33 This separation of the guide rollers at this time, due to the cause stated, does not however, result in a loosening of the the link31 and the hand lever 31' is made by a slot 31 in the former. It is further' more desirable, that when the blOW vpipe clutch and support have been actuated to re lease a blow pipe upon which an article has been finished, means be provided to restrain any tendency of the spring 17 to move'them from this position until another pipe has been inserted, and this is accomplished by a groove 3% in the rear end of the .rod .17, in which groove one end of a spring pressed trigger 34 is adapted to engage when the the end of the blow pipe contacting against the packing, and the chuck block 15 has an air passage 35* registering with the aperture 35 and connected with an air pipe 35" which passes through the trunnion 3 of the blow pipe frame and isflconnected' with proper mechanism for introducing blowing air. The chuck shell 15 has a gear 39upon its periphery which is driven by a pinion 39 on the rear end of a shaft 39 mounted on the under side of the bottom web of the blow pipe frame and having a gear 39 on its forward end meshing with a beveled idler 39 mounted in a bracket 39 on the bottom web of the blow pipe frame. The idler is driven by'the beveled gear 4E0 of the doubled face gearing 4O sleeved on the trunnion 3 of the blow pipe frame, thespur gearing d-O of the same being driven in any suitable man pipe support adapted to receive a remove able blow pipe and to becaused to engage the opposite ends thereof when desired to hold. the same rigid and to simultaneously release such ends when it is desired to remove 'the blow pipe; and one in which only one end of the blow pipe may be released when desired. l

The use of the double support for the blow pipe is especially desirable, when as in the apparatus forming part of myoriginal application, the glass upon the blow pipe is to be subjected to a marvering action prior to the molding, during which marvering it must be held with considerable rigidity to produce the required result. In the accompanying drawings, I have shown such a" marverer -at 50 and in the action of the machine the blow pipe carrying frame is swung upwardly and downwardly to carry the glass on the blow pipe along the face of the marvererwith a rolling action, whereby a shaping of the solid blank is obtained.-

Inasmuch as this application has been filed as a division of my prior application Serial Number 602,532, in response to re quirementsof division by the Patent Oflice and for the purpose of containing only the claims upon blow-pipe receiving, holding and releasing mechanism shown in such application, failure to claim herein features other than those relating to such mechanisms is not ,to be taken as a disclaimer by me of such mechanisms, as I have claimed certain of such other features more or less broadly in my other applications, viz, Se-

rial Number 602,532, before referred to, and" Serial Numbers 491,812, filed April 23, 1909, 551,198, filed March 23, 1910, and ratios, filed December 18, 1912. Y
